## 1

In a division problem, product of quotient and the remainder is 24 while their sum is 10. If the divisor is 5 then dividend is _______

## 32

Given that,

Quotient(Q) x Remainder(R) = 24

Quotient(Q) + Remainder(R) = 10

So, we have been given sum and product of the roots of a quadratic equation.

By observing, we can see that the roots should be 6 and 4 (6 x 4 = 24 and 6 + 4 = 10)

We do not know yet whether Quotient is 6 and Remainder is 4 or vice versa.

It is also given that the divisor is 5. From this we can infer that the remainder cannot be 6 as the divisor is 5.

Therfore Quotient = 6 ; Divisor = 5 ; Remainder = 4.

Dividend = (Divisor x Quotient) + Remainder

Dividend = (5 x 6) + 4

Dividend = 34

## 2

The shortest distance from the point (-4,3) to the circle x2+y2=0 is ___

## 4

From the above diagram, we can see that, we can draw many lines to the circle that can be a secant or a tangent. We need to find the line which gives us the shortest distance of the point from the circle.

It is very evident that the line joining the center of the cirle to the point (-4,3) will give us the shortest distance.

As we can see from the diagram, we have a right triangle with base length as 4 and height as 3. Therefore the distance of the point (-4,3) from the center of the circle is the hypotenuse and its length is 5. (3,4,5 is a pythagorean triplet)

Therefore, the distance of the point (-4,3) from the circle = 5 - radius of the circle = 5 - 1 = 4

## 3

The value of is ____

##

## 4

Suppose where a, b and c are distinct real numbers. If a= 3, then the value of abc is ____________

## 1

## 5

The minimum value of f(x)=|3-x|+|2+x|+|5-x| is equal to

## 6

Ashok purchased pens and pencils in the ratio 2: 3 during his first visit and paid Rs. 86 to the shopkeeper. During his second visit, he purchased pens and pencils in the ratio 4: 1 and paid Rs. I 12 . The cost of a pen as well as a pencil in rupees is a positive integer. If Ashok purchased four pens during his second visit, then the amount he paid in rupees for the pens during the second visit is __________.

## 100

Ratio of pen : pencil is 2:3 and he spends Rs 86

Next time The ratio of pen and pencil is 4:1 and he spends Rs 112

Second time Ashok purchased 4 pens, So the ratio of Pen and Pencil is 4:1

Hence he purchased 4 pens and 1 pencil during his second visit

Let price of pen be 'x' and price of pencil be 'y'

Then,

4x + y = 112. -----(2)

2x + 3y = 86 -----(1)----(From first visit)

(1) Is in Ratios, so it can be 4x + 6y = 86 (or)

6x + 9y = 86 (or)

8x + 12y = 86

Since, From (2), 4 pen and a pencil costs Rs 112

4 pens and 6 pencils has too cost more than 112 (Given that Cost of a pen and pencil is a positive integer)

In that case 4x + 6y = 86 (or)

6x + 9y = 86 (or)

8x + 12y = 86

These possibilities are ruled out

Only possibility is 2x + 3y = 86

Solving (1) and (2) by Elimination Method

We get y = 12 ---> Cost of a pen

On second visit, he pays a total of Rs 112, One pencil and 4 pen.

1 Pencil costs Rs 12, 112 - 12 = Rs 100

He paid Rs 100 during his second visit for the pens.

## 7

In a four-digit number, the product of thousands digit and units digit is zero while their difference is 7. Product of the middle digits is 18 . The thousands digit is as much more than the units digit as the hundreds digit is more than the tens digit. The four-digit number is __________.

## 7920

Given is a 4-digit number, Since the product of thousands digit and unit digit is zero.

One of them has to be zero. Thousandth Digit cannot be zero, since it is a 4-digit number

So, unit digit has to be zero.

__ __ __ 0

Given thousands place and unit place difference is 7

7 __ __ 0

Product of middle digits is 18

So, the possibilities are 3 × 6 or 6 × 3 or 2 × 9 or 9 × 2

Thousandth digit is more than unit digit by 7

Then the hundredth digit should be more than tens digit by 7. (since given thousandth digit is as much more than the unit digit as the hundreds digit is more than tens digit)

So it has to be 9 and 2

7 9 2 0

## 8

Out of 80 students who appeared for the school exams in Mathematics (M), Physics (P) and Chemistry (C), 50 passed M , 30 passed P and 40 passed C. At most 20 students passed M and P at most 20 students passed P and C and at most 20 students passed C and M. The maximum number of students who could have passed all three exams is __________.

## 20

M ∪ P ∪ C = 80 (assume 80 to get max value of x)

M ∪ P ∪ C = M + P + C - (M ∩ P) - (P ∩ C) - (M ∩ C)+ M ∩ P ∩ C

80 = 50 + 30 + 40 - (M ∩ P) - (P ∩ C) - (M ∩ C) + x

(M ∩ P) + (P ∩ C) + (M ∩ C) = 40 + x

At most 20

So, 20 + 20 + 20 = 40 + x

xmax = 20

## 9

Two friends run a 3-kilometer race along a circular course of length 300 meters. If their speeds are in the ratio 3:2, the number of times the winner passes the other is ______.

## 3

The faster of the two friends will catch up with the slower one only after he runs one extra round than the slower one.

Here since the ratio of the speeds of the two friends is 3 : 2

The faster of the two meets the slower one once every three rounds.

Since the track length is 300m and the race is of 3KM length, the faster of the number of rounds to finish the race is 3km/300m =10 rounds. Since they meet for every 3 rounds, and there are 10 rounds in total they meet 10/3= 3 times

## 10

Out of 13 objects, 4 are indistinguishable and rest are distinct. The number of ways we can choose 4 objects out of 13 objects is ________.

## 256

Since there are indistinguishable toys, only the number of such indistinguishable toys picked matter.

We may choose

0 indistinguishable toys & 4 distinct toys

1 indistinguishable toys & 3 distinct toys

2 indistinguishable toys & 2 distinct toys

3 indistinguishable toys & 1 distinct toys

4 indistinguishable toys & 0 distinct toys

So effectively, the number of ways of picking is ,

the number of ways of picking 4 distinct toys + the number of ways of picking 3 distinct toys + the number of ways of picking 2 distinct toys + the number of ways of picking 1 distinct toys + the number of ways of picking 0 distinct toys.

There are 13 - 4 = 9 distinct toys.

Therefore, the number of ways of picking =

## 11

The probability that a randomly chosen factor of 1019 is a multiple of 1015 is _______

## D. 1/16

1019 = 219 × 519

This is of the form 2x × 5y

x can take values from 0 to 19

y can take values from 0 to 19

x can take 20 vales and y can also take 20 values

Chosen number has 20 × 20 = 400 factors

Among that we need a number which is a multiple of 1015 = 215 × 515

This is of the form 2a × 5b

We need a number that is not only a multiple of 2a × 5b but also a factor of 219 × 519

Looking for numbers which are in form 2p × 5q

Since 2p × 5q is a factor of 219 × 519, p and q should be less than or equal to 19

Since 2p × 5q is a multiple of 215 × 515, p and q should be more than or equal to 15

p and q can take any of the 5 values 15, 16, 17, 18, 19.

So, the probability is 5×5/20×20 = 1/16

## 12

The number of acute angled triangles whose sides are three consecutive positive integers and whose perimeter is at most 100 is

## 29

Perimeter is at most 100

Since three consecutive integers, lets take random values

1, 2, 3

By triangle property sum of two sides has to be greater than third side

1 + 2 is not greater than 3

So, ruled out

Lets take 2, 3, 4

Acute angle property is Sum of square of any two sides has to be greater than square of third side

22 + 32 > 42

13 < 16. (So this condition is also not possible)

3, 4, 5 ----- Right angle triangle. (Not possible)

Lets take 4, 5, 6

42 + 52 > 62

41 > 36

This works (4,5,6)

Then (5,6,7) works

When the numbers become larger squares become increasingly larger

Numbers are close to each other, we are going closer to acute angle

So from (4,5,6),.......(32,33,34) everything satisfies this condition.

32,33,34 -Perimeter is at most 100

So, out of 32 Combinations, First 3 are ruled out. So in total 29 combinations

## 13

The equation of the straight line passing through the point M (-5,1), such that the portion of it between the axes is divided by the point M in to two equal halves, is

## A. 10y - 8x = 80

The point P divides AB into 2 halves.

AP = PB

A is on the x axis, Hence Point A (h,0)

B is on the Y axis, Hence Point B (0,k) We need to use midpoint formula.

[(h+0)/2 , (k+0)/2] = (-5 , 4)

h/2 = - 5 => h = -10 k/2= 4 => k = 8

## B. His love for botany went beyond borders.

The passage is generally about Mr. Muir's love for Botany, and it states that “Even at the early age of twenty-nine his eager interest in every aspect of the natural world had made him a citizen of the universe.” So, option C is the right choice.

Option A cannot be inferred from the passage.

From the passage, we know Mr. Muir wanted to more than just travel. He wanted to follow his passion by studying plants in their natural settings. So, option B is incorrect.

We don't know if Mr. Muir wanted to live in the open all his life. He did undertake a 1000-mile journey but that wasn't to experience the open as much as it was to study the natural world and "botanize", as the passage calls it. So, option D is ruled out.

## 32

## A. Finding food among the farmers.

Note these lines in the passage: ‘"Oftentimes," Mr. Muir writes in some unpublished biographical notes, "I had to sleep out without blankets, and also without supper or breakfast. But usually I had no great difficulty in finding a loaf of bread in the widely scattered clearings of the farmers.’ Hence, the answer is "Finding food among the farmers".

## 33

## A. He felt spiritually fulfilled.

The passage quotes Mr. Muir saying “With one of these big backwoods loaves I was able to wander many a long, wild mile, free as the winds in the glorious forests and bogs, gathering plants and feeding on God's abounding, inexhaustible spiritual beauty bread.” So, Mr. Muir felt spiritually fulfilled after his experience with nature.

## 34

## C. His eyesight was affected, but he was able to carry on

Note the line in the passage where Mr. Muir writes to his friend after the injury: "I have been reading and botanizing for some weeks, and find that for such work I am not very much disabled."

## 35

## B. studied plants in their natural habitat

From the passage, we gather that Mr. Muir went on scientific expeditions, to study plants in their natural settings. So, ‘to botanize’ is to study plants, especially in their natural habitat.

## 36

## B. There was a cloud over the landscape he travelled

Option B is incorrect: the cloud was not over the landscape Mr. Muir travelled, but in his vision as he viewed the landscapes through his injured eye.

We know option A is true, based on the line "I was eager to see Illinois prairies on my way home, so we went to Decatur, near the center of the State, thence" in the passage.

The last few lines refer to the account written by Mr. Muir after the excursion and his statement that "To me all plants are more precious than before". So, options C and D are true.

## 37

It came as a shock to me that my friend had lost his ___________ in a moment of madness as he lent all of it to his neighbour.

## A. Nest egg

A 'nest egg' refers to savings put aside for a specific purpose.

## 38

During the debate, when the minister appeared to be vague about his stand on the controversial energy project, his opponent asked him to ___________ and declare outright if the government would go ahead with the project or not.

## B. cut to the chase

To 'cut to the chase' is to come to the point and deal with what is important, instead of talking about or engaging in less important things.

## 39

It is irritating when co-workers dismiss your ideas as worthless, and later present those very ideas as their own. They just want to ___________.

## C. steal your thunder

To steal someone's thunder is to do what they were going to do before they do it, thus taking away success or attention away from them.

## 40

Before the start of the meeting, I am ___________ on the latest developments.

## C. going to bring you up to speed

To bring someone ‘up to speed’ is to update them with all the latest information about something.

## 41

Despite statistics to prove that there was a slowdown in the economy of the country, the professor was ___________ about it.

## B. in denial

To be ‘in denial’ is to refuse to admit the truth, especially when the truth is something unpleasant.

## 42

After the unearthing of relics at the archacological site, the historian was asked to ___________ the significance of the discovery.

## A. throw light on

To ‘throw light’ on something is to explain it well, thereby making it easier to understand.

## 43

The pharmaceutical company hired a consultant to supervise a taskforce studying lower salaries as to their effects on employees' morale.

## B. studying the effects of lower salaries on employee morale

A taskforce 'studying the effect of lower salaries on employee morale' is correct.

Option D states the exact opposite of what is given. 'Studying what...' is incorrect usage

## 44

Besides offering physiological rewards such as toned muscles, when regular karate is practiced the body can be turned into a dangerous weapon.

## D. karate, if practiced regularly, can turn the body into a dangerous weapon

The error in the given sentence is that of a dangling modifier. "Besides offering physiological rewards such as toned muscles..." is a modifier that refers to an action (offering rewards) but does not state what offers these rewards. Such modifiers must be followed immediately after by the subject they modify. In other words, “Besides offering physiological rewards such as toned muscles” must be followed immediately after by “karate”, which is the subject of the main clause. So, option D is correct.

## 45

The animal activist has raised awareness not only on the plight of abandoned dogs, but also on overworked bulls and temple elephants.

## B. not only on the plight of the abandoned dogs, but also on that of overworked bulls

There is a parallelism error in the given sentence. The element that follows 'not only' says 'on the plight of abandoned dogs', but the element that follows 'but also' simply states 'on overworked bulls and temple elephants' without referring to 'the plight'. This error is corrected in option B, which uses the pronoun ‘that’ instead of the noun ‘the plight’.

## 46

When people move from one city or country to another, the spread of diseases may result. People often bring in germs which may not have been present there before. These new germs can spread quickly and cause previously unknown diseases. __________________________________. They become ill more easily and could even die. In turn, newcomers may catch diseases which were not present where they came from.

## C. If a germ is completely new to a region, people have no natural protection against it.

The sentence before the blank talks of germs spreading quickly, while the sentence after the blank talks of people falling ill more easily. The only sentence among the given options that connects these two ideas is C.

## 47

Samar, a young man from a village in Tripura is a social media star who hopes to make it big as a model and actor. While his minute-long videos are very popular, his series titled, "Who wore it better? showcases his creative side. He uses a variety of filters and visual effects to improve his videos. _______.

## D. This shows how it is possible today for people with limited resources to express their creativity.

The paragraph given is about a young man from a village achieving popularity by making creative videos on social media. Only option D touches upon all ideas in the paragraph.

## 48

Coral reefs are one of the most ___________, biologically complex, and diverse marine ecosystems on Earth. This ecosystem is one of the ___________ paradoxes of the biosphere: how do clear, and thus nutrient-poor, waters support such ___________ and productive communities?

## B. fragile, fascinating, prolific

For the first blank, only 'common' (option A) and 'fragile' (option B) fit. 'Most deep' is incorrect; the correct word would be 'deepest'. The word 'frail' is usually used to refer to people, not inanimate objects.

So, for the second blank, we have to choose between 'sensitive' and 'fascinating'. Of the two, 'fascinating' is apt. A paradox cannot be described as sensitive.

'Prolific’ fits well in blank 3. So, option B is the correct answer.

## 49

It is a ___________ to live in a land without ___________. Even with all the technological advancement and economic growth, there are still millions who live in war zones where life every day is filled with ___________.

## B. privilege, bigotry, terror

For the first blank, all options except 'lovely' (option C) fit. But, examining the second blank, we can rule out options A (It is a coincidence to live in a land without prejudice) and D (It is a punishment to live in a land without hate) as they do not make meaningful sentences. 'It is a privilege to live in a land without bigotry' makes the best sense. Option B.

## 50

The ability to ___________ and ___________ a cohesive team is particularly critical in hi-tech firms where the ___________ landscape can shift dramatically in the face of disruptive technologies.

## B. shape, guide, competitive

Blank 3 is key to solving this question, as it is not possible to eliminate options using the first two blanks. The sentence talks about a dramatically changing landscape. The word 'competitive' fits this context best. Option B.

## 51

Cool-headed and rational, Jo Eun-cha is a talented and driven anchorman who commands as well as demands respect. After ___________ to get elected as a news director, he aims to ___________ to his job as the top news anchor to increase his ___________ of being elected next year.

## B. failing, return, chances

For the first blank, 'failing' is the best fit. Jo Eun-cha's job as an anchorman brings him respect. So, returning to this job after failing to get elected could possibly improve his chances of being elected the next year. Option B.

## 52

A collective investment fund (CIF), also known as a collective investment trust (CIT), is a group of ___________ accounts held by a bank or trust company. The financial institution ___________ assets from individuals and organizations to ___________ a single larger, diversified portfolio.

## D. pooled, groups, develop

For the first blank, all options except 'different' (option B) fit. For the second blank, we can eliminate option C as 'collected' is in the past tense, while the given lines are in present tense. Option A, too, is not a good fit for blank 2. Option D is the best choice.

## 53

C. My uncle who lives in New York tumed out to be the exact opposite of the urbane, wealthy gentleman that I was expecting to meet.

D. Over 70% of the people living in urbane areas said that they wanted better roads and more schools.

## D. Over 70% of the people living in urbane areas said that they wanted better roads and more schools.

The adjective 'urbane' is used to describe a polished person who handles himself confidently in social situations. This word is used correctly in all sentences except D, where the word 'urban'(related to a city) is appropriate.

## 54

One of the statements below contains a word used incorrectly. Choose the option which has the incorrect or inappropriate usage of the word.

A. The young scientist built a small, low-cost machine to recycle waste water. It was a simple but ingenious solution to the problem of water shortage in the city.

D. Teachers say that some children are very ingenious when it comes to finding excuses for not completing their work.

## C. The young man lost all his savings because he was rather ingenious to believe the agent's promises of a well-paid job and a comfortable life in a foreign country.

The adjective ‘ingenious’ is used to describe a clever person or a skillfully made/planned thing. This word is used correctly in all sentences except C. The word 'ingenuous' (showing childlike innocence) is the right one to use in statement C.

## 55

One of the statements below contains a word used incorrectly. Choose the option which has the incorrect or inappropriate usage of the word.

A. After several rounds of meetings, the city council passed an ordinance to limit the number of cafes near the seaside.

B. As per a royal ordinance, all men under 18 had to join the army and fight the war.

C. Military aircrafts can be used to carry a wide variety of ordinance.

D. The people protested a city ordinance that all parks must be closed by 9 pm.

## C. Military aircrafts can be used to carry a wide variety of ordinance.

The word ‘ordinance’ refers to an authoritative rule or regulation. This word is used correctly in all sentences except C. In sentence C, ‘ordnance’ (military weapons and ammunition) is the right word to use.

## 56

One of the statements below contains a word used incorrectly. Choose the option which has the incorrect or inappropriate usage of the word.

A. It is a pleasure when we are all together for a meal at home.

B. Her son is not interested in watching movies, which is not all together a bad thing.

C. The three hundred guests sat all together in the large dining hall of the hotel.

D. The facilitator asked the participants to stand up, all together.

## B. Her son is not interested in watching movies, which is not all together a bad thing.

While altogether means ‘on the whole’ or ‘all things considered’, all together means ‘everyone/everything together.’ In sentence B, altogether is appropriate, not all together.

## 57

One of the statements below contains a word used incorrectly. Choose the option which has the incorrect or inappropriate usage of the word. A. The sickness of a family member can affect the lives of everyone at home.

B. Kerala was affected by severe Nood all through the year.

C. Taking this medicine for a prolonged period can have severe after affects.

D. The popular star was not a natural actor: his style was rather affected.

## C. Taking this medicine for a prolonged period can have severe after affects.

To affect something is to influence it. This is a verb. The result of being affected is an effect. An effect is a noun. In sentence C, the word ‘effects’ is appropriate.

## 58

The sentences given below, when properly sequenced, form a coherent paragraph. Each sentence is labelled with a number. Decide on the most logical order and enter the sequence of numbers in the space provided. A. However, they stand out because they help the film maker realize his personal artistic vision.

B. An Indie film refers to independent films made outside a major studio system.

C. Their release is also limited to a few screens, although there have been films with a wide release.

D. Most of such films are low budget films produced and distributed by small companies.

## BDCA

Sentence B is the best start to the paragraph, as it states what an Indie film is. D adds to B, explaining how 'such films' are produced and distributed. C logically follows up on this explaining how these films are released. So, BDC is a unit. Sentence A concludes the paragraph well, stating why Indie films stand out despite being small-scale. So, BDCA is the correct order.

## 59

The sentences given below, when properly sequenced, form a coherent paragraph. Each sentence is labelled with a number. Decide on the most logical order and enter the sequence of numbers in the space provided.

A. Mental illness continues to struggle for recognition as a significant contributor to poor health in spite of the existence of the Mental Healthcare Act 2017

B. The data reveals that an estimated one in seven Indians - or 197 million persons suffered from mental disorders, at varying degrees of severity, in 2017.

C. There is always more to human health than meets the eye.

D. This is particularly important in the Indian cultural and political context, where the outward appearance of physical well-being is often considered the only visible marker of overall health.

## CDAB

There are two possibilities for the opening sentence of the paragraph-- A and C. So, let us look at how the ideas in the sentences link to each other. CD is a link. D adds to the point made in C, considering the Indian context. AB is also a link: sentence A talks about mental illness not being recognized as a significant contributor to poor heath and B follows this up with data. CDAB is a better order than ABCD as C offers a more general start to the paragraph than A. So, CDAB is the correct order.

## 60

The sentences given below, when properly sequenced, form a coherent paragraph. Each sentence is labelled with a number. Decide on the most logical order and enter the sequence of numbers in the space provided. A. It was felt that the major polluters had a moral obligation to deliver on the agreements reached some years ago during a similar convention on Climate Change.

B. The papers presented indicated that the impacts of current warming are much more severe than previously understood.

C. It appears that the planet's ability to adapt to and cope with how it is being treated is fraying.

D. For example, the acceleration of sea level rise and ocean warming, and increasing risks of reaching limits to adaptation

E. This is what emerged at a recent conference attended by the largest scientific community on climate science.

## CDEBA

C is the most general statement and is hence the best opening sentence. The example in D adds to C. So, we have the link CD. E fits in best after D, as CD explains the phrase 'this is what emerged' in E. Sentence E talks about 'a recent conference'; sent B talks about the papers presented in the conference and sentence A, the conclusion reached. So, we have the order CDEBA.
